Atari Buys Intellivision Brand, Ending 'Longest-Running Console War in History' 54

An old-school video game rivalry has a new chapter: Atari, known for producing one of the first hit home game consoles, has announced the acquisition of long-time rival Intellivision's brand and rights to over 200 games from Intellivision Entertainment. The two companies were key players in the industry's first console war in the late 1970s and early 1980s. Atari plans to expand distribution of Intellivision games and explore new opportunities for the brand. Mike Mika, studio head at Digital Eclipse, an Atari-owned game studio, commented on the deal, saying the acquisition "ends the longest-running console war in history."

US Securities Regulator Urges Against Crypto Bill Adoption 39

The U.S. securities regulator on Wednesday urged U.S. lawmakers not to adopt a bill that aims to create a new legal framework for digital currencies, saying it would undermine existing legal precedent and put capital markets at "immeasurable risk." From a report: The U.S. House of Representatives is expected later on Wednesday to take up the Republican-sponsored Financial Innovation and Technology for the 21st Century Act, which would in part determine which agencies have jurisdiction over which digital assets. The bill's supporters in Congress say it will provide regulatory clarity, helping promote the industry's growth.

The legislation faces an uncertain fate in the U.S. Senate but comes as the U.S. Securities and Exchange Commission (SEC) signals that it will likely approve applications for spot ether exchange-trade funds in a surprising boost to the industry. But SEC Chair Gary Gensler said in a statement that the bill "would create new regulatory gaps and undermine decades of precedent regarding the oversight of investment contracts, putting investors and capital markets at immeasurable risk."

Gordon Bell, an Architect of Our Digital Age, Dies At Age 89 (arstechnica.com) 6

An anonymous reader quotes a report from Ars Technica: Computer pioneer Gordon Bell, who as an early employee of Digital Equipment Corporation (DEC) played a key role in the development of several influential minicomputer systems and also co-founded the first major computer museum, passed away on Friday, according to Bell Labs veteran John Mashey. Mashey announced Bell's passing in a social media post on Tuesday morning. "I am very sad to report [the] death May 17 at age 89 of Gordon Bell, famous computer pioneer, a founder of Computer Museum in Boston, and a force behind the @ComputerHistory here in Silicon Valley, and good friend since the 1980s," wrote Mashey in his announcement. "He succumbed to aspiration pneumonia in Coronado, CA."

Bell was a pivotal figure in the history of computing and a notable champion of tech history, having founded Boston's Computer Museum in 1979, which later became the heart of the Computer History Museum in Mountain View, with his wife Gwen Bell. He was also the namesake of the ACM's prestigious Gordon Bell Prize, created to spur innovations in parallel processing.
Bell also mentored at Microsoft in 1995, where he "studied telepresence technologies and served as the subject of the MyLifeBits life-logging project," reports Ars. "The initiative aimed to realize Vannevar Bush's vision of a system that could store all the documents, photos, and audio a person experienced in their lifetime."

Former Windows VP Steven Sinofsky said Bell "was immeasurably helpful at Microsoft where he was a founding advisor and later full time leader in Microsoft Research. He advised and supported countless researchers, projects, and product teams. He was always supportive and insightful beyond words. He never hesitated to provide insights and a few sparks at so many of the offsites that were so important to the evolution of Microsoft."

"His memory is a blessing to so many," added Sinofsky in a post memorializing Bell. "His impact on all of us in technology will be felt for generations. May he rest in peace."

Match Group, Meta, Coinbase And More Form Anti-Scam Coalition (engadget.com) 23

An anonymous reader shares a report: Scams are all over the internet, and AI is making matters worse (no, Taylor Swift didn't giveaway Le Creuset pans, and Tom Hanks didn't promote a dental plan). Now, companies such as Match Group, Meta and Coinbase are launching Tech Against Scams, a new coalition focused on collaboration to prevent online fraud and financial schemes. They will "collaborate on ways to take action against the tools used by scammers, educate and protect consumers and disrupt rapidly evolving financial scams."

Meta, Coinbase and Match Group -- which owns Hinge and Tinder -- first joined forces on this issue last summer but are now teaming up with additional digital, social media and crypto companies, along with the Global Anti-Scam Organization. A major focus of this coalition is pig butchering scams, a type of fraud in which a scammer tricks someone into giving them more and more money through trusting digital relationships, both romantic and platonic in nature.

EPA Says It Will Step Up Enforcement To Address 'Critical' Vulnerabilities Within Water Sector (therecord.media) 64

The U.S. Environmental Protection Agency on Monday urged water utilities to take action to improve their digital defenses, following a spate of recent cyberattacks. From a report: The agency's "enforcement alert" said that recent inspections of water systems found that more than 70 percent fail to meet basic cybersecurity standards, including some with "critical" vulnerabilities, such as relying on default passwords that haven't been updated and single logins that "can easily be compromised." The notice comes after a Russian hacktivist group claimed credit for digital assaults on water sites in Texas and Indiana. Late last year, Iran-linked Cyber Av3ngers group took responsibility for striking a water authority in Pennsylvania.

Google Cuts Mystery Check To US In Bid To Sidestep Jury Trial (reuters.com) 38

An anonymous reader quotes a report from Reuters: Alphabet's Google has preemptively paid damages to the U.S. government, an unusual move aimed at avoiding a jury trial in the Justice Department's antitrust lawsuit over its digital advertising business. Google disclosed (PDF) the payment, but not the amount, in a court filing last week that said the case should be heard and decided by a judge directly. Without a monetary damages claim, Google argued, the government has no right to a jury trial. The Justice Department, which has not said if it will accept the payment, declined to comment on the filing. Google asserted that its check, which it said covered its alleged overcharges for online ads, allows it to sidestep a jury trial whether or not the government takes it.

The Justice Department filed the case last year with Virginia and other states, alleging Google was stifling competition for advertising technology. The government has said Google should be forced to sell its ad manager suite. Google, which has denied the allegations, said in a statement that the Justice Department "manufactured a damages claim at the last minute in an attempt to secure a jury trial." Without disclosing the size of its payment, Google said that after months of discovery, the Justice Department could only point to estimated damages of less than $1 million. The company said the government has said the case is "highly technical" and "outside the everyday knowledge of most prospective jurors."

38% of Webpages That Existed in 2013 Are No Longer Accessible a Decade Later 62

A new Pew Research Center analysis shows just how fleeting online content actually is: 1. A quarter of all webpages that existed at one point between 2013 and 2023 are no longer accessible, as of October 2023. In most cases, this is because an individual page was deleted or removed on an otherwise functional website.
2. For older content, this trend is even starker. Some 38% of webpages that existed in 2013 are not available today, compared with 8% of pages that existed in 2023.

This "digital decay" occurs in many different online spaces. We examined the links that appear on government and news websites, as well as in the "References" section of Wikipedia pages as of spring 2023. This analysis found that:
1. 23% of news webpages contain at least one broken link, as do 21% of webpages from government sites. News sites with a high level of site traffic and those with less are about equally likely to contain broken links. Local-level government webpages (those belonging to city governments) are especially likely to have broken links.
2. 54% of Wikipedia pages contain at least one link in their "References" section that points to a page that no longer exists.[...]

Linux Foundation Announces Launch of 'High Performance Software Foundation' (linuxfoundation.org) 4

This week the nonprofit Linux Foundation announced the launch of the High Performance Software Foundation, which "aims to build, promote, and advance a portable core software stack for high performance computing" (or HPC) by "increasing adoption, lowering barriers to contribution, and supporting development efforts."

It promises initiatives focused on "continuously built, turnkey software stacks," as well as other initiatives including architecture support and performance regression testing. Its first open source technical projects are:

- Spack: the HPC package manager.

- Kokkos: a performance-portable programming model for writing modern C++ applications in a hardware-agnostic way.

- Viskores (formerly VTK-m): a toolkit of scientific visualization algorithms for accelerator architectures.

- HPCToolkit: performance measurement and analysis tools for computers ranging from desktop systems to GPU-accelerated supercomputers.

- Apptainer: Formerly known as Singularity, Apptainer is a Linux Foundation project providing a high performance, full featured HPC and computing optimized container subsystem.

- E4S: a curated, hardened distribution of scientific software packages.

As use of HPC becomes ubiquitous in scientific computing and digital engineering, and AI use cases multiply, more and more data centers deploy GPUs and other compute accelerators. The High Performance Software Foundation will provide a neutral space for pivotal projects in the high performance computing ecosystem, enabling industry, academia, and government entities to collaborate on the scientific software.

The High Performance Software Foundation benefits from strong support across the HPC landscape, including Premier Members Amazon Web Services (AWS), Hewlett Packard Enterprise, Lawrence Livermore National Laboratory, and Sandia National Laboratories; General Members AMD, Argonne National Laboratory, Intel, Kitware, Los Alamos National Laboratory, NVIDIA, and Oak Ridge National Laboratory; and Associate Members University of Maryland, University of Oregon, and Centre for Development of Advanced Computing.

In a statement, an AMD vice president said that by joining "we are using our collective hardware and software expertise to help develop a portable, open-source software stack for high-performance computing across industry, academia, and government." And an AWS executive said the high-performance computing community "has a long history of innovation being driven by open source projects. AWS is thrilled to join the High Performance Software Foundation to build on this work. In particular, AWS has been deeply involved in contributing upstream to Spack, and we're looking forward to working with the HPSF to sustain and accelerate the growth of key HPC projects so everyone can benefit."

The new foundation will "set up a technical advisory committee to manage working groups tackling a variety of HPC topics," according to the announcement, following a governance model based on the Cloud Native Computing Foundation.

Robot Dogs Armed With AI-aimed Rifles Undergo US Marines Special Ops Evaluation (arstechnica.com) 74

Long-time Slashdot reader SonicSpike shared this report from Ars Technica: The United States Marine Forces Special Operations Command (MARSOC) is currently evaluating a new generation of robotic "dogs" developed by Ghost Robotics, with the potential to be equipped with gun systems from defense tech company Onyx Industries, reports The War Zone.

While MARSOC is testing Ghost Robotics' quadrupedal unmanned ground vehicles (called "Q-UGVs" for short) for various applications, including reconnaissance and surveillance, it's the possibility of arming them with weapons for remote engagement that may draw the most attention. But it's not unprecedented: The US Marine Corps has also tested robotic dogs armed with rocket launchers in the past.

MARSOC is currently in possession of two armed Q-UGVs undergoing testing, as confirmed by Onyx Industries staff, and their gun systems are based on Onyx's SENTRY remote weapon system (RWS), which features an AI-enabled digital imaging system and can automatically detect and track people, drones, or vehicles, reporting potential targets to a remote human operator that could be located anywhere in the world. The system maintains a human-in-the-loop control for fire decisions, and it cannot decide to fire autonomously. On LinkedIn, Onyx Industries shared a video of a similar system in action.

In a statement to The War Zone, MARSOC states that weaponized payloads are just one of many use cases being evaluated. MARSOC also clarifies that comments made by Onyx Industries to The War Zone regarding the capabilities and deployment of these armed robot dogs "should not be construed as a capability or a singular interest in one of many use cases during an evaluation."

Are AI-Generated Search Results Still Protected by Section 230? (msn.com) 63

Starting this week millions will see AI-generated answers in Google's search results by default. But the announcement Tuesday at Google's annual developer conference suggests a future that's "not without its risks, both to users and to Google itself," argues the Washington Post: For years, Google has been shielded for liability for linking users to bad, harmful or illegal information by Section 230 of the Communications Decency Act. But legal experts say that shield probably won't apply when its AI answers search questions directly. "As we all know, generative AIs hallucinate," said James Grimmelmann, professor of digital and information law at Cornell Law School and Cornell Tech. "So when Google uses a generative AI to summarize what webpages say, and the AI gets it wrong, Google is now the source of the harmful information," rather than just the distributor of it...

Adam Thierer, senior fellow at the nonprofit free-market think tank R Street, worries that innovation could be throttled if Congress doesn't extend Section 230 to cover AI tools. "As AI is integrated into more consumer-facing products, the ambiguity about liability will haunt developers and investors," he predicted. "It is particularly problematic for small AI firms and open-source AI developers, who could be decimated as frivolous legal claims accumulate." But John Bergmayer, legal director for the digital rights nonprofit Public Knowledge, said there are real concerns that AI answers could spell doom for many of the publishers and creators that rely on search traffic to survive — and which AI, in turn, relies on for credible information. From that standpoint, he said, a liability regime that incentivizes search engines to continue sending users to third-party websites might be "a really good outcome."

Meanwhile, some lawmakers are looking to ditch Section 230 altogether. [Last] Sunday, the top Democrat and Republican on the House Energy and Commerce Committee released a draft of a bill that would sunset the statute within 18 months, giving Congress time to craft a new liability framework in its place. In a Wall Street Journal op-ed, Reps. Cathy McMorris Rodgers (R-Wash.) and Frank Pallone Jr. (D-N.J.) argued that the law, which helped pave the way for social media and the modern internet, has "outlived its usefulness."

The tech industry trade group NetChoice [which includes Google, Meta, X, and Amazon] fired back on Monday that scrapping Section 230 would "decimate small tech" and "discourage free speech online."

The digital law professor points out Google has traditionally escaped legal liability by attributing its answers to specific sources — but it's not just Google that has to worry about the issue. The article notes that Microsoft's Bing search engine also supplies AI-generated answers (from Microsoft's Copilot). "And Meta recently replaced the search bar in Facebook, Instagram and WhatsApp with its own AI chatbot."

The article also note sthat several U.S. Congressional committees are considering "a bevy" of AI bills...

The Delta Emulator Is Changing Its Logo After Adobe Threatened It (theverge.com) 56

After Adobe threatened legal action, the Delta Emulator said it'll abandon its current logo for a different, yet-to-be-revealed mark. The issue centers around Delta's stylized letter "D", which the digital media giant says is too similar to its stylized letter "A". The Verge reports: On May 7th, Adobe's lawyers reached out to Delta with a firm but kindly written request to go find a different icon, an email that didn't contain an explicit threat or even use the word infringement -- it merely suggested that Delta might "not wish to confuse consumers or otherwise violate Adobe's rights or the law." But Adobe didn't wait for a reply. On May 8th, one day later, Testut got another email from Apple that suggested his app might be at risk because Adobe had reached out to allege Delta was infringing its intellectual property rights.

"We responded to both Apple and Adobe explaining our icon was a stylized Greek letter delta -- not an A -- but that we would update the Delta logo anyway to avoid confusion," Testut tells us. The icon you're seeing on the App Store now is just a temporary one, he says, as the team is still working on a new logo. "Both the App Store and AltStore versions have been updated with this temporary icon, but the plan is to update them to the final updated logo with Delta 1.6 once it's finished."

WD Rolls Out New 2.5-Inch HDDs For the First Time In 7 Years (tomshardware.com) 63

Western Digital has unveiled new 6TB external hard drives -- "the first new capacity point for this hard drive drive form factor in about seven years," reports Tom's Hardware. "There is a catch, though: the HDD is slow and will unlikely fit into any mobile PCs, so it looks like it will exclusively serve portable and specialized storage products." From the report: Western Digital's 6TB 2.5-inch HDD is currently used for the latest versions of the company's My Passport, Black P10, and G-Drive ArmorATD external storage devices and is not available separately. All of these drives (excluding the already very thick G-Drive ArmorATD) are thicker than their 5 TB predecessors, which may suggest that in a bid to increase the HDD's capacity, the manufacturer simply installed another platter and made the whole drive thicker instead of developing new platters with a higher areal density.

While this is a legitimate way to expand the capacity of a hard drive, it is necessary to note that 5TB 2.5-inch HDDs already feature a 15-mm z-height, which is the highest standard z-height for 2.5-inch form-factor storage devices. As a result, these 6TB 2.5-inch drives will unlikely fit into any desktop PC. When it comes to specifications of the latest My Passport, Black P10, and G-Drive ArmorATD external HDDs, Western Digital only discloses that they offer up to 130 MB/s read speed (just like their predecessors), feature a USB 3.2 Gen 1 (up to 5 GT/s) interface using either a modern USB Type-C or Micro USB Type-B connector and do not require an external power adapter.

France Bans TikTok In New Caledonia (politico.eu) 48

In what's marked as an EU first, the French government has blocked TikTok in its territory of New Caledonia amid widespread pro-independence protests. Politico reports: A French draft law, passed Monday, would let citizens vote in local elections after 10 years' residency in New Caledonia, prompting opposition from independence activists worried it will dilute the representation of indigenous people. The violent demonstrations that have ensued in the South Pacific island of 270,000 have killed at least five people and injured hundreds. In response to the protests, the government suspended the popular video-sharing app -- owned by Beijing-based ByteDance and favored by young people -- as part of state-of-emergency measures alongside the deployment of troops and an initial 12-day curfew.

French Prime Minister Gabriel Attal didn't detail the reasons for shutting down the platform. The local telecom regulator began blocking the app earlier on Wednesday. "It is regrettable that an administrative decision to suspend TikTok's service has been taken on the territory of New Caledonia, without any questions or requests to remove content from the New Caledonian authorities or the French government," a TikTok spokesperson said. "Our security teams are monitoring the situation very closely and ensuring that our platform remains safe for our users. We are ready to engage in discussions with the authorities."

Digital rights NGO Quadrature du Net on Friday contested the TikTok suspension with France's top administrative court over a "particularly serious blow to freedom of expression online." A growing number of authoritarian regimes worldwide have resorted to internet shutdowns to stifle dissent. This unexpected -- and drastic -- decision by France's center-right government comes amid a rise in far-right activism in Europe and a regression on media freedom. "France's overreach establishes a dangerous precedent across the globe. It could reinforce the abuse of internet shutdowns, which includes arbitrary blocking of online platforms by governments around the world," said Eliska Pirkova, global freedom of expression lead at Access Now.

Another Billionaire Pushes a Bid For TikTok, But To Decentralize It (techdirt.com) 68

An anonymous reader quotes a report from Techdirt, written by Mike Masnick: If you're a fan of chaos, well, the TikTok ban situation is providing plenty of chaos to follow. Ever since the US government made it clear it was seriously going to move forward with the obviously unconstitutional and counterproductive plan to force ByteDance to divest from TikTok or have the app effectively banned from the U.S., various rich people have been stepping up with promises to buy the app. There was former Trump Treasury Secretary Steven Mnuchin with plans to buy it. Then there was "mean TV investor, who wants you to forget his sketchy history" Kevin O'Leary with his own TikTok buyout plans. I'm sure there have been other rich dudes as well, though strikingly few stories of actual companies interested in purchasing TikTok.

But now there's another billionaire to add to the pile: billionaire real estate/property mogul Frank McCourt (who has had some scandals in his own history) has had an interesting second act over the last few years as a big believer in decentralized social media. He created and funded Project Liberty, which has become deeply involved in a number of efforts to create infrastructure for decentralized social media, including its own Decentralized Social Networking Protocol (DSTP).

Over the past few years, I've had a few conversations with people involved in Project Liberty and related projects. Their hearts are in the right place in wanting to rethink the internet in a manner that empowers users over big companies, even if I don't always agree with their approach (he also frequently seems to surround himself with all sorts of tech haters, who have somewhat unrealistic visions of the world). Either way, McCourt and Project Liberty have now announced a plan to bid on TikTok. They plan to merge it into his decentralization plans.
"Frank McCourt, Founder of Project Liberty and Executive Chairman of McCourt Global, today announced that Project Liberty is organizing a bid to acquire the popular social media platform TikTok in the U.S., with the goal of placing people and data empowerment at the center of the platform's design and purpose," reads a press release from Project Liberty.

"Working in consultation with Guggenheim Securities, the investment banking and capital markets business of Guggenheim Partners, and Kirkland & Ellis, one of the world's largest law firms, as well as world-renowned technologists, academics, community leaders, parents and engaged citizens, this bid for TikTok offers an innovative, alternative vision for the platform's infrastructure -- one that allows people to reclaim agency over their digital identities and data by proposing to migrate the platform to a new digital open-source protocol. In launching the bid, McCourt and his partners are seizing this opportunity to return control and value back into the hands of individuals and provide Americans with a meaningful voice, choice, and stake in the future of the web."

EU Opens Child Safety Probes of Facebook and Instagram, Citing Addictive Design Concerns (techcrunch.com) 48

An anonymous reader quotes a report from TechCrunch: Facebook and Instagram are under formal investigation in the European Union over child protection concerns, the Commission announced Thursday. The proceedings follow a raft of requests for information to parent entity Meta since the bloc's online governance regime, the Digital Services Act (DSA), started applying last August. The development could be significant as the formal proceedings unlock additional investigatory powers for EU enforcers, such as the ability to conduct office inspections or apply interim measures. Penalties for any confirmed breaches of the DSA could reach up to 6% of Meta's global annual turnover.

Meta's two social networks are designated as very large online platforms (VLOPs) under the DSA. This means the company faces an extra set of rules -- overseen by the EU directly -- requiring it to assess and mitigate systemic risks on Facebook and Instagram, including in areas like minors' mental health. In a briefing with journalists, senior Commission officials said they suspect Meta of failing to properly assess and mitigate risks affecting children. They particularly highlighted concerns about addictive design on its social networks, and what they referred to as a "rabbit hole effect," where a minor watching one video may be pushed to view more similar content as a result of the platforms' algorithmic content recommendation engines.

Commission officials gave examples of depression content, or content that promotes an unhealthy body image, as types of content that could have negative impacts on minors' mental health. They are also concerned that the age assurance methods Meta uses may be too easy for kids to circumvent. "One of the underlying questions of all of these grievances is how can we be sure who accesses the service and how effective are the age gates -- particularly for avoiding that underage users access the service," said a senior Commission official briefing press today on background. "This is part of our investigation now to check the effectiveness of the measures that Meta has put in place in this regard as well." In all, the EU suspects Meta of infringing DSA Articles 28, 34, and 35. The Commission will now carry out an in-depth investigation of the two platforms' approach to child protection.

Wallet Recovery Firms Buzz as Locked-out Crypto Investors Panic in Bitcoin Boom (reuters.com) 35

The recent surge in bitcoin prices has the phones at crypto wallet recovery firms ringing off the hook, as retail investors locked out of their digital vaults make frantic calls to regain access to their accounts. From a report: Cryptocurrencies exist on a decentralized digital ledger known as blockchain and investors may opt to access their holdings either through a locally stored software wallet or a hardware wallet, to avoid risks related to owning crypto with an exchange, as in the case of the former FTX. Losing access to a crypto wallet is a well-known problem. Investors forgetting their intricate passwords is a primary reason, but loss of access to two-factor authentication devices, unexpected shutdowns of cryptocurrency exchanges and cyberattacks are also common.

Wallet passwords are usually alphanumeric and the wallet provider also offers a set of randomized words, known as "seed phrases," for additional security - both these are known only to the user. If investors lose the passwords and phrases, access to their wallets is cut off. With bitcoin prices regaining traction since last October and hitting a record high of $73,803.25 in March, investors seem to be suffering from a classic case of FOMO, or the fear of missing out. Reuters spoke to nearly a dozen retail investors who had lost access to their crypto wallets. Six of them contacted a recovery services firm and managed to regain access to their holdings.

Quantum Internet Draws Near Thanks To Entangled Memory Breakthroughs (newscientist.com) 47

An anonymous reader quotes a report from New Scientist: Efforts to build a global quantum internet have received a boost from two developments in quantum information storage that could one day make it possible to communicate securely across hundreds or thousands of kilometers. The internet as it exists today involves sending strings of digital bits, or 0s and 1s, in the form of electrical or optical signals, to transmit information. A quantum internet, which could be used to send unhackable communications or link up quantum computers, would use quantum bits instead. These rely on a quantum property called entanglement, a phenomenon in which particles can be linked and measuring one particle instantly influences the state of another, no matter how far apart they are. Sending these entangled quantum bits, or qubits, over very long distances, requires a quantum repeater, a piece of hardware that can store the entangled state in memory and reproduce it to transmit it further down the line. These would have to be placed at various points on a long-distance network to ensure a signal gets from A to B without being degraded.

Quantum repeaters don't yet exist, but two groups of researchers have now demonstrated long-lasting entanglement memory in quantum networks over tens of kilometers, which are the key characteristics needed for such a device. Can Knaut at Harvard University and his colleagues set up a quantum network consisting of two nodes separated by a loop of optical fibre that spans 35 kilometers across the city of Boston. Each node contains both a communication qubit, used to transmit information, and a memory qubit, which can store the quantum state for up to a second. "Our experiment really put us in a position where we're really close to working on a quantum repeater demonstration," says Knaut. To set up the link, Knaut and his team entangled their first node, which contains a type of diamond with an atom-sized hole in it, with a photon that they sent to their second node, which contains a similar diamond. When the photon arrives at the second diamond, it becomes entangled with both nodes. The diamonds are able to store this state for a second. A fully functioning quantum repeater using similar technology could be demonstrated in the next couple of years, says Knaut, which would enable quantum networks connecting cities or countries.

In separate work, Xiao-Hui Bao at the University of Science and Technology of China and his colleagues entangled three nodes together, each separated by around 10 kilometers in the city of Hefei. Bao and his team's nodes use supercooled clouds of hundreds of millions of rubidium atoms to generate entangled photons, which they then sent across the three nodes. The central of the three nodes is able to coordinate these photons to link the atom clouds, which act as a form of memory. The key advance for Bao and his team's network is to match the frequency of the photons meeting at the central node, which will be crucial for quantum repeaters connecting different nodes. While the storage time was less than Knaut's team, at 100 microseconds, it is still long enough to perform useful operations on the transmitted information.

Walmart's Reign as America's Biggest Retailer Is Under Threat (wsj.com) 48

With Amazon on its heels, the nation's biggest company by revenue is hunting for ways to continue growing. From a report: For a decade, Walmart has reigned as the nation's biggest company by revenue. Its sales last year added up to $648 billion -- more than $1.2 million a minute. That status comes with benefits. It gives Walmart power in negotiations with product manufacturers and in dealing with government officials over policy issues. It's also a point of pride: Job postings often tout working at the "Fortune 1" company as a perk. Its reign is looking shaky lately [non-paywalled link]. If current sales trends persist, Amazon is likely to overtake Walmart soon. Amazon reported $575 billion in total revenue last year, up 12% from the previous year, compared with Walmart's revenue growth of 6%.

Walmart's behemoth size means that to meet its own sales target of around 4% growth each year, the company has to find an additional $26 billion in sales this year. That's no easy task. About 90% of Americans already shop at the retailer. The pandemic and rising inflation boosted Walmart's revenue by $100 billion since 2019. It faces continued uncertainty in consumer confidence and while it's spending in some areas, it's pulling back in others. Earlier this week, Walmart told workers it would cut hundreds of corporate jobs and ask most remote workers to move to offices. While Amazon's and Walmart's businesses compete head on, there are big differences. Amazon earns much of its profit from non-retail operations such as cloud computing and advertising, while grabbing retail market share with fast shipping. Walmart gets the bulk of its sales and profits from U.S. stores, while growing side businesses like advertising and digital sales.

Walmart executives are most wary of Amazon's ability to keep increasing profits through its non-retail business, while eating more of the retail landscape with ever-faster shipping and a bigger product selection, people familiar with the company said. Internally some executives are highlighting Walmart's role as a good corporate citizen and emphasizing that it's important to be the best at serving customers and workers, not just the biggest, say some of those people. Its scale can also have downsides, say some, like outsize attention on every misstep.

'Roaring Kitty' Trader Returns, Causing GameStop Shares To Jump More Than 70% (cbsnews.com) 33

GameStop shares surged over 72% on Monday after Keith Gill, also known as "Roaring Kitty," returned to social media following a three-year hiatus. Gill gained notoriety for his role in the 2020 meme stock frenzy, where he encouraged amateur investors to buy GameStop shares, significantly driving up the stock price and challenging hedge funds. From a report: He resurfaced on X, Sunday night, with an image of a sketched man leaning forward in a chair, marking the end of a roughly three-year hiatus. He followed that post with several others featuring various comeback-themed videos featuring movie clips and charged music.

GameStop had experienced declining sales amid an industrywide pivot from game cartridges to video game streaming and digital downloads, but with the help from meme stock investors, last March the company turned its first profit in two years. Before then, the company had posted seven straight quarterly losses. This January, GameStop reported its first annual profit since 2018. Roaring Kitty's post helped bump GameStop's share price to $28.25 on Monday. GameStop's all-time high stock price is $120.75 in January 2021.
